All state AG offices have a form for consumer complaints on their website. Usually it's very easy to find. Don't overthink it. Mention the letter in your AG complaint, include a copy and the date that you sent it. They will contact the business and start a resolution process. Usually you'll hear back in a week or so.
AFAIK, every state's attorney general's office will have an online site and/or form for filing complaint(s), as well as a postal address you can use.
You can free-form your own letter, though that might delay things somewhat from the AG's office, though the business / countereparty will typically get on their game quickly.
DDG "consumer complaint" + <YOUR_STATE_HERE> should work.
